Roof Replacement

New Hampshire's Weather Demands a Roof That Can Take It

Between heavy snow loads, ice dams, nor'easters, and summer storms, your roof takes more punishment in Southern NH than in most parts of the country. When it's time for a replacement, you need a contractor who understands these conditions and installs with the precision to withstand them.

Prescott Roofing specializes in complete asphalt shingle roof replacements for homes across Hillsborough, Rockingham, and Merrimack counties. We use top-tier materials from manufacturers like GAF, Owens Corning, and CertainTeed, and every installation is backed by both manufacturer and workmanship warranties.

What's Included in Every Roof Replacement

Every Prescott Roofing replacement follows the same systematic process — no shortcuts, no exceptions. Here's what you get:

• Complete tear-off of existing roofing materials down to the deck
• Full deck inspection — we repair or replace any damaged or soft plywood sheathing
• Ice & water shield membrane along eaves, in valleys, and around all penetrations
• Premium synthetic underlayment across the entire roof surface
• New aluminum drip edge along eaves and rakes
• Architectural shingle installation with manufacturer-spec nailing patterns
• Step and counter flashing at all walls, chimneys, and penetrations
• Ridge vent installation for balanced attic ventilation
• Pipe boot and vent flashing replacement
• Complete cleanup with magnetic nail sweep of the yard and landscaping
• Final walkthrough and quality inspection with you

Shingle Options: Good, Better, Best

We install architectural shingles from the industry's top manufacturers. Each tier offers increasing wind resistance, warranty coverage, and aesthetic appeal. Here's how the most popular lines compare:

All shingles in our lineup carry algae-resistance technology and Class A fire ratings. The "Better" and "Best" tiers unlock enhanced system warranties from the manufacturer when paired with matching starter strips, ridge caps, and underlayment — covering both materials and labor for the full warranty period. During your inspection, we'll recommend the tier that fits your priorities and budget.

Typical NH Project Timeline

From first call to final cleanup, here's what a typical residential roof replacement looks like:

1. 1

   Free Inspection (Day 1)

   We assess your roof's condition, photograph findings, and discuss options. You get a written estimate — no pressure.

2. 2

   Material Selection (Days 2-3)

   Choose your shingle line, color, and warranty tier. We order materials and schedule the install.

3. 3

   Installation (Days 5-10)

   Typical installs take 1-3 days depending on home size and complexity. We protect landscaping, complete the tear-off, inspect the deck, and install your new roof system.

4. 4

   Final Walkthrough

   We walk the property with you, point out the work, run a magnetic nail sweep, and make sure you're satisfied before we leave.

What Affects Replacement Cost

Every roof is different. These factors influence the scope and price of your replacement:

• Roof size (measured in roofing squares — 1 square = 100 sq ft)
• Pitch/steepness — steep roofs require more safety equipment and labor time
• Number of existing layers to tear off (one layer vs. two adds labor and disposal)
• Decking condition — soft or rotted plywood must be replaced before shingling
• Roof complexity — dormers, valleys, hips, and multiple planes add material and labor
• Access — tight lots, landscaping obstacles, or multi-story homes affect staging
• Material choice — Good/Better/Best tiers carry different material costs
• Ventilation upgrades — adding or expanding ridge vents, soffit vents, or baffles

We provide a detailed, line-item written estimate so you know exactly what you're paying for — no surprises at the end.

Insurance vs. Retail: Two Paths to a New Roof

Insurance path:If storm damage triggered the replacement, we handle the entire claims process. We document damage with Xactimate-formatted estimates, meet your adjuster on-site, and file supplements when the initial scope doesn't cover everything. Most homeowners with legitimate storm damage pay only their deductible for a full replacement.

Retail path:If your roof has simply aged out or you prefer not to file a claim, we offer competitive pricing and flexible financing options. You get the same materials, the same precision installation, and the same warranties — just a different payment path. We'll work with you to find the right product tier and payment option for your budget.
